10   - Anup Patel <anup@brainfault.org>
13   The RISC-V advanced interrupt architecture (AIA) defines an advanced
15   in a RISC-V platform. The RISC-V AIA specification can be found at
16   https://github.com/riscv/riscv-aia.
18   The RISC-V APLIC is implemented as hierarchical APLIC domains where all

46       RISC-V HARTS (or CPUs). Each node pointed to should be a riscv,cpu-intc
47       node, which has a CPU node (i.e. RISC-V HART) as parent.
